VENTILATING-SHUTTER.

Specification of Letters Patent.

Patented Mar. 12, 191$.

Application filed July 7, 1917. eria1 No. 179,119.

To all whom it may concern:

Be it known that JOSEPH C. GOODMAN, a citizen of the United States of America, residing at Columbus, in the county of Frank lin and State of Ohio, has invented certain new and useful Improvements in Ventilating-Shutters, of which the following is a specification.

T he present invention relates to improvements in ventilating shutters designed espe cially for use in railroad cars, street railway cars, and other vehicles, and the invention is also adapted for use as a ventilator for residences Or other buildings.

In its adaptation to railroad car windows the invention is primarily designed to perform the function of a ventilating device and at the same time act as guard against the ingress of cinders, dust, dirt, etc. I

The invention consists in certain novel combinations and arrangements of vertically arranged slats in a frame adapted for installation in the window frame, as will be hereinafter more fully pointed out and claimed.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention constructed and arranged according to the best mode I have so far devised for the practical application of the principles of my invention.

Figure 1 is a view in elevation of the complete ventilating device.

Fig. 2 is a horizontal sectional view of the ventilator located in position, the window frame also being in section.

Fig. 3 is a vertical sectional view showing the device in position.

Fig. 4 is an enlarged, fragmentary, view of the device in longitudinal section.

Fig. 5 is an enlarged, fragmentary, view of the device, in vertical section.

In order to illustrate the adaptation and installation of my invention I have utilized a typical window frame with the usual sill 1, and jambs 2, 2, which frame may be thatof a railroad or railway car, and for purposes of consideration and description of its function and operation the ventilating device will be referred to in connection with this car window.

The ventilating device is made up of a plurality of vertically arranged slats, fixed in two alternating series, as 3, 3, and 4, 4, etc., in the frame 5. The frame 5 is preferably of metal, being illustrated of angle iron shapes, and the frame which is rectangular in formation is adapted tofit neatly in the window frame from the outside thereof suitable means being employed to hold the frame in place.

The slats comprising the two series are also made of metal, rolled or pressed into exact counterparts of each other, each slat comprising a plate 6 which is rolled or curved over to form an end pocket 7 from which diverges the angular flange 8. These slats are soldered together in pairs, as indicated at 9, the joint being made at the backs of the pockets so that the angular openings of the slats face in opposite directions. These pairs of slats are arranged in the metallic frame 5 so that'the plates 6 of the I slats in the alternating series overlap, as clearly seen in Fig. 4, and provide a channel therebetween, as indicated at 10 and this channel has an ingress, tapering opening 11 gradually dimishing toward its pocket, and

an outwardly flaring egress opening 12 through the pocket of the opposite slat. All oints are soldered around the edges of the metal frame of the ventilator, as at 13, so I that einders or dust cannot gain egress to the interior of the car, and as seen in Fig. 4 especially, a major portion of each one of the slats is located without or beyond the window frame. Thus assuming the ventilator to be in the window of a car traveling in the direction indicated by the arrow in Fig. 4, it will be seen that currents of air are caught within the flaring flange 8 of alternating slats, and pass in the direction of the small arrows through the opening 11, the channel 10, and thence out through the opening 12 into the interior of the car. The cinders, .dust, dirt, etc., however, are

caught in the vertically extending pocket of dustguard, the combination with a frame I and two series of alternating slats fixed therein, each slat having a plate and a curved end portion forming a pocket and a radially extending outwardly flaring flange, and the plates of the alternating slats overlapping to form an ingress opening, a dust pocket, a reverse channel, and an outlet opening parallel with the inlet opening.

2. In a ventilating device the combination with a suitable frame, of a pair of slats formed with parallel, overlapping plates having bent end portions and parallel flaring flanges oppositely projected from the bent end portions, said structure forming an ingress opening, a reverse channel, and an outlet opening parallel with the inlet open- 1n %n testimony whereof I afiix my signature.

JOSEPH C. GOODMAN.
